Sinx=\frac{opposite}{hypotenuse} =\frac{ \sqrt{2} }{2}
     opposite=\sqrt{2}
     hypotenuse=2

Adjacent^{2}+(\sqrt{2 })^{2 }= 2 ^{2}
<span>Adjacent^{2}+2=4
</span><span>Adjacent^{2}=2 
</span>Adjacent=\sqrt{2}

cosx=\frac{ajc}{hyp}= \frac{ \sqrt{2} }{2}
Tanx=\frac{opp}{adj} =  \frac{ \sqrt{2} }{ \sqrt{2} }

Answer:

Step-by-step explanation:

Principal, P = $4,000

Interest rate, r = 3% = 0.03

Period, t = 20 years

Number of times compounded in a year = 4

Amount , A = P( 1 + r/n)^tn

A = 4000( 1 + 0.03/4)^4*20

A = 4000( 1 + 0.0075) ^80

A =4000( 1.0075) ^80

A = 4000* 1.818

A = $7272.18
